VSI Vertical Shaft Impact Crusher

Mining Machines overviews

Adopting quality raw materials and advanced technologies, VSI Vertical Shaft Impact Crusher ensures high-quality and good abrasion performance. This machine switches the working principle “crushing between materials” to “crushing between materials and liners”, which can be used to make sand and shape stones.

Advantages:

1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation. 2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity. 3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance. 4. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it. 5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally. 6. Special feed opening structure makes it possible that center feeding and ring feeding comes together, in order to meet requirement of different stones. In addition, this equipment can not only crush stone, but also iron.

Working Principle

1. Center Feeding: Raw material falls down into feed hopper, then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards through outlet. 2. Ring Feeding: Raw material falls down into feed hopper, then through ring, it is divided into two parts by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.
